HC, was playing with prime membership features and thinking I might have found a process that could be easier for you. Rather than loading 5000 caches in GSAK, the GC.com website has the ability to sort by last find. If you set your search to downtown (or where ever you normally search from) and sort the by last find youngest to oldest, you could then just download the list to a GPX (OK a couple of GPX). Then you could upload those GPX into GSAK and use it to run comparisons, or filter out inactive, or whatever. Just a thought.

Quoting an old post -- for what it's worth, this is basically how I did my report this month. I just did a search from the downtown coords that I use for my PQ's, sorted by last found (oldest first), then skipped over the events and as yet unfound caches -- and there was my list! The standard GC search goes out 50 miles -- how convenient. I still had to pull up each cache and check it for who found it last and how many DNF's, etc, but it was no more work intensive than my old method. No PQ's to download and no chance of missing a recently unarchived cache. Sweet!

Well since I was unable to attend the 11-11-11 event in The Woodlands today and the Clear Lake one is a little far for me. I had my own celebration. I found two caches on the list. Both have been on the list for some time.

A TROLL HOME 2 GC1AQKH - was last found on 2/22/09 by trea and PDXJim with five DNF's since.

I spend less than five minutes at this cache before I found it. Sometimes you just get lucky.

Up You Go GC1BNBV - was last found on 8/14/09 by The Pirate Kid with two DNF's since.

I went here during lunch and realized after I left I was projecting from the wrong point. I then went back after work and made quick work of it. Finding the cache in a few minutes.
